Let x gallons be the amount of milk containing 9% butterfat and y gallons be that of milk containing 1% butterfat.

We have $$\begin{cases}x + y = 244\\(9\%)x + (1\%)y = (7\%)(244)\end{cases}$$ by considering the total amount of milk and the total amount of butterfat respectively.

Can you continue solving for x and y from here?
